To really enhance the sound of the VQ37VHR, specially designed ø48.6 mm headers were developed, helping flowexhaust gasses more freely towards the sports catalysts and the rest of the system. The stacked tail pipes may look a little Lexus IS-F, but are a kind of modern interpretation of the S30's stacked twin pipes. With a specially tuned ECU governing the V6, power is boosted by 38 HP and response improved. Hiding behind the forged monobloc Central20 C5 19-inch wheels is a pretty serious brake upgrade with massive 6-pot calipers biting down on 370 mm rotors and 4-pots at the rear mated to slightly smaller 355 mm discs. The Z rides on Central20 coilover suspension, offering up a fine combination of comfort and precision. The interior will satisfy anyone out there with a serious carbon fiber fetish.
